I’m sorry you had such a difficult time.
Hospital wards are not the nicest places and having a traumatic birth and being sleep deprived are both awful things to go through.
I think you did the right thing by letting your DH go home and sleep.
Hopefully he can take you home today and be safe to drive and then let you sleep as much as you can.
The first couple of days I would absolutely prioritise sleep and take shifts if you need to whilst you’re both adjusting to the massive change.
Ultimately, what’s done is done.
They kept you in the main ward for safety and this is what you need to focus on, even if you felt they didn’t check on you much.
Health care staff are often able to look like they’re not busy or not constantly watching but actually if something did happen to you, then they’d have noticed almost immediately.
The only reason you don’t know this is because fortunately your recovery was ok.
You have to drop this as over analysing something like this can make things like PND worse.
You will have some trauma from a difficult birth already and you don’t have the energy to give this anymore thought.
Congratulations on your new baby 💐
